GEA’s water-saving membrane system for non-alcoholic beer

GEA AromaPlus PRO reduces the water consumption for diafiltration throughout dealcoholization by as a lot as 100%. The alcoholic base produced as a by-product of the filtration course of can be used for manufacturing different beverages within the brewery, such as hard seltzer.
GEA AromaPlus uses a filtration technology with special polymer membranes to separate alcohol and water from the opposite ingredients by means of reverse osmosis; these ingredients are crucial for the aroma, colour and turbidity of the final product. Adding the brand new PRO expertise to the water-saving CO2 blow-out perform and the selective membrane which is already applied in the AromaPlus unit design, GEA saves more than two thirds and up to one hundred pc of the fresh water used for diafiltration.
“Our latest AromaPlus generation combines the development in the path of zero.0% beer with the objective of reducing water in production,” says Ralf Scheibner, filtration skilled at GEA, underneath whose management the GEA AromaPlus has been additional developed. “In truth, a membrane process requires a lot of water to flush out the alcohol. That is a matter for breweries with a limited deoxygenized water availability. Our new PRO solution is a crucial step for them in the path of fresh water neutrality in manufacturing processes.”

The full dealcoholization system GEA AromaPlus is mounted on a body. It contains the filtration modules and reverse osmosis membranes, pumps for media switch and system strain build-up, the whole inside piping, a CIP dosing unit put in next to the system, and the control tools required for semi-automated operation. – Image: GEA/Mike Henning.
While breweries want less fresh water for the diafiltration step, the permeate leaving the system can be reused as a useful by-product. diaphragm seal to its decrease quantity, it has the next alcohol content material and may subsequently serve as a base for alcoholic mixed drinks and newer beverages, corresponding to exhausting seltzer, or can be reused within the brewery itself.
“The Corona pandemic showed that breweries whose production facilities supplied the pliability to course of other drinks coped greatest with the drop in demand. GEA AromaPlus is an effective example of how prospects can gear their plants towards excessive demand dynamics,” says Scheibner. Originally designed for the dealcoholization of beer all the means down to 0.0%, the system can also be used used for other non-alcoholic beverages, corresponding to zero.0% cider.
